This invention relates tofnew and usefulY improvements in what are known by cottonmanufacturers as rin g-spinnin g frames,77 (having more particular reference to the throstleframe,)"whereby the operation of spinning is greatly improved, both as regards the work performed and the expense attending it and the invention consists in a device for preventing the spindle from trembling vvor vibrating when running at a high speed.

Figure l represents a vertical sectionof a throstle-spinning frame with dead-spindles, showing the tube and bobbin on the spindles, and other features which embrace our invention, the section being through theline a' .fr of Fig. 2. Fig. 2 is a top 0r plan view of the same, showing the division-plates between the spindles. Fig. 3 is a vertical sectional view of one side of the frame, showing the parts at full siz e. Fig. 4 is a horizontal section of Fig. 3 through y y. Fig.'5 is a longitudinal section through the line z z of Fig. 3.

Similar letters of reference indicate corresponding parts.

A represents the spindle-rail or frame, to which the spindle is secured. B is the spindle. C is the tube around the spindle. D is the bobbin on the tube. 4E is the ring-rail. F is the angular bar by which the ring-rails E are connected. G represents the spring which We apply to the spindle to prevent jar and vibration when running at a high rate of speed. H is the brake by which the motion of the tube is stopped when itis necessary to mend the thread or for other purposes. I represents the division-plate between the spindles. J is the drum, from which the tubes are revolved by means of the cords K.

The usual method of holding the dead-spindle in the frame is by a set-screw, which of Specification forming partof "Letters PatentzNofS'mQ 16, dated July 21, 'l i i' course confines it' rigidly in the-frame. For a moderate motion,`this method is not particu` larly objectionable, `butin running at a highf "rate 'of speed, the'jarring and'vibration conscvquent upon the rigidv confinement of' the spin dle bythe set-screw interferes more or less to defeat the object in view.

' g We have found that by giving the spindle (which is loosely placed `in its bearings) a certain degree of elasticity byjapplying to it af slight pressure,by means of a spring orsorne Vother elasticsubstance, We can 'run at a' high speed without jar or vibration." We are thereby enabled to do work which we could not do with spindles` `rigidly-set in theY frame-inthe usual manner. 1

To accomplish our obj e'ctwe apply the spring G to the spindle, substantially asV seen in the drawing. The spring bears against the spindle at two point`s,`as shown inthe drawing, andas the spindle is allowed a slight play in its bear ings, its tendency to vibrate undera high rate of f speed is overcome by the spring. Any movement of the upper end of the spindle would be communicated to the lower end, and canse the spring to yield in a corresponding degree, and prevent the return motion necessary to vibration.

L is an adjustable support to which the spring is attached, and the pressure is regu- 'latedby the screws fm from the frame A.

It will be seen that there is a circular groove in the spindle at a, into which one end of the spring sets. This is to prevent the spindle from being raised from its step in the frame.

The ring-rails of the frame are rigidly attached to the ends of the connecting-bar F at each side, and the device for raising and lowering (whether by gearing or other methods) is applied directlyto the bar, thereby producing a steady and uniform motion in the rails,

and adding greatly to the regularity and completeness of the operation.

The division-plate I is a flat piece of metal, attached to the ring-rail between the spindles at its lower end, and extending up nearly or quite to the top of the bobbin.

As the threads vibrate in consequence of their rapid rotating motion, the plate prevents them from coming in collision, as they not m1- frequently do without such a guard between them.

Thefring-rail is ordinarily formed with two pendent anges, i. We dispense with one of 1 these anges, as seen in the drawing, for the purpose of dropping the ring-rail lower down', and at the same time clearing the drivingcord K. i

In forming the bobbin, we do` not chamber it in boring, as is usually done, but bore it of uniform size from the bottom endv to near the top, the upper 'end being bored to fit thel tube, as seen in the drawing. The tube being turned to two diii'erent sizes, leaves a chamber between them, as seen, and also enables us' to make the tube larger immediately above the grooved pulley, thereby adding to its strength where strength is mostneeded. This method of boring the' bobbinandturning the tube saves the use of an expensive tool for forming the chamber, and greatly simplifies and lcheapens the cost of the bobbins. The ordinary method has been to bore the bobbin with a hole of uniform size, andvthen chamber it outwith an expanding tool.

The method of lubricating the spindle isseen at '0, Figs. l and 5. An oil-chamber is drilled.

into the end ofthe spindle, into which the lubrieating-oil is poured,'which oil is discharged through a hole bored laterally'to thevrst, as seen in the drawing. Aw'ck or some brous or absorbing material is placed in the hole in thel spindle for retaining. the oil, and allowing' it to be discharged gradually for the required.` lubrication.
